Subthreshold Time‐Mode All‐Digital DLL With Built‐In Linearization
International Journal of Circuit Theory and Applications, EarlyView.This paper presents a subthreshold time‐mode all‐digital delay‐locked loop (DLL) for low‐frequency clock generation. The large and tunable delay of the DLL is obtained using a static inverter delay line whose supply voltage is in the vicinity of 100 mV and adjustable by varying supply voltage. Phase error is processed by a time‐mode proportional block (
